' In Sweden September 12, 193i 6 Claims.

This invention relates to certain new and useful improvements in packing boxes for packing goods, and more particularly to packing boxes for packing delicate goods such as glass, in-

struments and the like, and its particular object is to obtain an improved device in such packing boxes in order to prevent shocks and blows on' the' packing's from being transmitted to the packed goods; another object of this invention is to make it possible to store the cartons in stores and during transport in a suitable manner.

More particularly the invention has for its object a packing box consisting of an outer carton of corrugated cardboard, pasteboard, and the like, and. an interior carton of the same material, located in the outer carton at some inter mediate space from the walls of the outer carton. In the intermediate space are provided resilient or yielding spacer members integral with, or provided on the walls of one carton, or of both cartons, said spacer members being adapted to abut against the other carton. Preferably the spacer members consist of ribs of corrugated cardboard, pasteboard, wood or the like secured to the walls, top and bottom of the interior carton, said ribs serving to receive shocks et cetera on the outer carton, for which purpose the ribs are of such a size that they can abut against the outer carton. Thus special loose fillers, such as wood fibre, sawdust, paperstrips, or fillers of 7 other material, are unnecessary.

A further feature of the packing box comprising an outer and an interior carton as stated above is that the two cartons are collapsible or foldable at their edges and provided with top and bottom cover members adapted to be opened and closed so that when open the cartons may be flattened with the sides of the carton lying against each other, in order to facilitate the storing and transport of the cartons.

The above and other objects of the invention will appear from the following description, and be illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of an embodiment of the invention with the interior carton a little drawn out;

Figure 2 is a section along the line II-II of Figure 1; and

Figures 3 and 4 are the outer and the interior carton respectively, with the top and bottom covers folded out, and the cartons in a partly, fiattened position;

Figure 5 is a view corresponding to Figure 2' of a somewhat modified embodiment.

said flaps being foldable along cuts 4a toward the In the embodiment shown in Figures 1-4 the two cartons constituting the packing box, the outer 2, as well as the interior 3 located in the outer carton at some distance from the walls of the outer, consist of a sheet of corrugated card- 5 board, pasteboard or the like, the said sheet being folded along three cuts t or the like, and with its end edges secured to each other by means of rivets 5, tacks, paste tape or the like so that the carton obtains a rectangular cross section, the cuts and the connection line respectively forming the edges of the carton. On line with the cuts the carton sheet is slit on both sides so that four'fiaps or lids 6 are formed on each side,

15 respective opening ofthe carton in order to form the top and bottom'cover respectively, two opposite flaps being folded preferably edge against edge, and the other two being folded over the first-mentioned flaps and secured to each other. When the flaps are folded out the carton may consequently 'be flattened as indicated in Figures 3 and 4.

Of course, the' respective carton may also be designed in'another way, for example with a tri- 25 angular or other (pentagonal, hexagonal et cetera) section, and, if desired, be composed of several parts secured to each other by means of paste tape, tacks et cetera. The flaps are then arranged in a suitable manner so that they can be folded for the indicated purpose.

On the outside of the walls 1 of the interior carton and on two opposite, i. e. outer flaps 6 are secured a number of ribs 8 or the like, in the example two on each wall and on each flap respectively, running at right angles to the cuts and slot edges respectively, said ribs consisting of corrugated cardboard, pasteboard, fibres, wood and the like, and being secured to the carton by means of paste tape 9 or in another way (rivets, tacks 40 et cetera). Preferably the ribs shown in the embodiment may consist of'a number of superposed pasteboard strips. If desired, the ribs may be integral with the carton by pressing or folding them out from parts of the walls of the carton. The ribs which serve as spacer members between the interior and the outer carton are of a size to conform to the space between the cartons so that when assembling the packing box the spacer members will abut against the outer carton, and thus receive the shocks and blows to which the outer carton is subjected, and prevent said shocks and blows from being transmitted to the packed article by the, to a certain extent, resilient walls et cetera of the interior carton, and moreover they increase the resistance of the packing to outer pressure. Of course, the number of the ribs is determined by the size of the carton, the weight and appearance vof the article to be packed et cetera. The ribs are disposed at such a distance from each other that the shocks et cetera are not transmitted directly to the interior carton. Further they should be placed so as to facilitate the insertion of the interior 'cartoniin the outer'cartcn, andconsequently par'al'lelto the insertion direction.

Preferably after the bottom cover of the terior carton has been closed,,with-theeribepro vided flaps outermost and joined1b'y-1meansuof1 paste tape, or in some suitable, preferably easily detachable way, the article irrquestion =is-packbdi in the carton, and then the=-top; c0ver,isncloseds.

in the indicated manner. Then the intericrcarton is introduced into the outer carton subsequent to the bottom of said outer carton-having;

if desired, been closedaccordingto the manner indicated above, whereby the cartonspreferablm should be so dimensioned relativelyto each other. that the sides glued together or fixed in some other way, i. e. the cover andbottomctthe in terior carton, will be placed against whole sides- (i. e. wallrportions) of the outer carton. Thusthe resistanceof the packing to outer pressure is increased. s Figure 5.is a modified embodiment in which theribs 8 are triangular-withone of the small sides provided with a flange-shaped continuation ill to increase the fixing surface. The. other features of the embodiment agree with that; of Figures 1-4.

This invention includes the following great advantages: the risk that shocks and'blows on the "outer. carton are transmitted to the packed article is greatly reduced; the packing is very;

resistant to outerpressure; further whenthe spacer members are rigidly secured to the int-- terior cartononly two elements are-* at: hand (thus, as a rule, no loose interior fillers:whicht are hard to adjust andretain in their places) the packing and mounting ioperationi'is considerably;

facilitated; the spacer memberscanbe exactly held in suitable positions; due'rto the foldabilityv of the cartons their packing and storing::.in.stores; and during transport likewise are facilitated.

Of course, the above embodimentsare only;

chosen as an example to explain the invention, and a great many variations'are possible without going beyond the scope of the invention. Thus the ribs may be secured to the insides of the outer carton, or be pressed out on said insides instead of on the interior carton, or said ribs may be provided or pressed out on the interior as well as on the outer carton.
